The importance of integrating herbarium records into conservation plans: a case study on Honduran ferns and lycophytes

open access: yesPLANTS, PEOPLE, PLANET, Volume 8, Issue 4, Page 1238-1255, July 2026.
Herbarium collections are powerful, yet underutilized, tools for global biodiversity conservation and protected area management. By integrating digitized herbarium records with existing biodiversity data, previously unknown plant species were uncovered, exposing critical gaps in conservation knowledge.

Tracing holotype trajectories: Mapping the movement of the most valuable herbarium specimens

open access: yesPLANTS, PEOPLE, PLANET, Volume 8, Issue 4, Page 1304-1321, July 2026.
Global efforts to protect biodiversity depend on fair access to key plant specimens. This study examines the distribution of 119,361 holotypes—unique herbarium specimens used to formally describe new plant species. By linking collection and storage data, we found that holotypes are increasingly held closer to their places of origin, particularly in ...

When growth form fossilizes: the description of a new liverwort species of the family Metzgeriaceae from the Cretaceous Las Hoyas site, with insights into its architecture and life mode

open access: yesPalaeontology, Volume 69, Issue 4, July/August 2026.
Abstract Examining the liverwort fossil collection from the Las Hoyas site, which was previously classified as Thallites sp., led to the discovery of a new species of Metzgeriales: Metzgeriites gynothallicus. This species is characterized by the presence of both asexual (propagule branches) and sexual (female branches bearing sporophytes) reproductive ...

Occurrence of galls in Microgramma mortoniana (Polypodiopsida: Polypodiaceae) from a subtropical forest, Brazil

open access: yesLilloa, 2020
The galls are structures formed of plant tissues in response to the activity of different types of organisms, especially by insects. As a consequence of an intimate relationship with their host plants, most of these insects have a very narrow host range.

Detecting Forest Water‐Availability and Biomass Patterns Through a Retrospective Study in a Mediterranean Region

open access: yesWater Resources Research, Volume 62, Issue 5, May 2026.
Abstract Latent heat (λ $\lambda $ET) fluxes are a major component of the hydrological cycle globally. According to recent models and experimental observations, during droughts, wetter regions respond by increasing λ $\lambda $ET, while drier regions exhibit decreasing trends due to vegetation water stress.

A Global, Taxon‐Stratified, High‐Resolution Sampling‐Effort Dataset From GBIF for Bias‐Aware Ecological Modelling

open access: yesDiversity and Distributions, Volume 32, Issue 5, May 2026.
ABSTRACT Introduction and Aim Spatiotemporal and taxonomic sampling bias in biodiversity occurrence data poses critical challenges for robust ecological inference, species distribution models (SDMs), and conservation planning. Despite the exponential growth in global biodiversity records over recent decades, these biases persist.
